Bombus hypnorum; Bombus pratorum
Mixed bumblebee species — mostly Bombus hypnorum and Bombus pratorum — foraging amongst cotoneaster in a disused suburban parking space.
I suspect Bombus hypnorum was nesting in a nearby garage, which had fallen into disrepair and had developed a number of small holes below the roof ideal for access/protection. There were perhaps 50 or more bumblebees around the entire plant (which stretched over a nearby fence), and I listened for some time before attaching a couple of small, omnidirectional microphones directly using clothes pegs.
Nearby dried vegetation and tree leaves moved as I recorded in moderate winds.
Bumblebees was played during BBC Radio 4's 'Slow Radio' feature on March 11, 2018. Listen here, from 18m 38s (sign-in required): https://www.bbc.co.uk/programmes/b09tyzh0.
